SPECIFICATION forming part of Letters Patent No. 228,270, dated June 1, 1880.

Application filed April 6, 1880.

To all whom t may concern,

Be it known that I, DAVID H. NATION, of St. Louis, Missouri, have made a new and useful Improvement in Ranges, of which the following is a full, clear, and exact'deseription, reference being had to the annexed drawings, making part of this specification, in which- Figure l is a top view of the improved range, a portion of the top plate being broken 1o away; Fig. 2, a bottom view, the bottom plate being removed; and Figs. 3, 4, details, being vertical sections taken, respectively, on the line a; x and the line y y of Fig. 1.

The same letters denote the same parts.

The present construction is an additional modification of one I have previously made, in which the features and advantages of a range and a three-flue cook-stove are combined.

The special advantage oi'this form ofthe range zo is that the top of the range is thoroughly utilized, there being no blank or unoccupied spaces in the top plate between the opening. But a single division-strip is used in forming the ues at the top of the range, and but a single damper is needed. The box-tine used in the former construction is done away with. The.

oven is not cut into, and the construction generally is simpler.

Referring to the drawings, A represents the 3o improved range, having the lire-place B, the

tlue G, leading from the lire-place, the divingues D D, the side bottom ues, E E, the center bottom flue, F, the ascending ue G, the

flue-space H, the escape-flue I, and the oven J.

3 5 A strip, K, extends from the back side, c, of

the range to the front side, c. It is arranged on the farther (measured from the fire-place) side of the diving-fines, and the parts are so (No model.)

proportioned as to bring the strip just between two sets of the openings in the top plate, a2, of 4o the range-say between the set L3 L3 and the set L4 L4. This enables all the openings Ll L L2 L2 L3 L3 L4 LL1 to be brought compactly together, as shown, and thereby the capacity of the range is increased.

M M represent a two-wing damper, by means of 'which the direct communication between the lues G and H can be closed-that is, there are openings l d just beneath the strip K, through which the heat-currents can pass from the ue C across the upper ends of the ues D D into the flue-'space H, and this is the course the heat-currents are allowed to take when it is not desired to heat the oven, but only the upper part of the range, and as 55 indicated in Fig. l. But to heat the oven the damper is turned up, as shown in Figs. 3, 4, and the heat-currents then pass from the tlue U down the diving-lines D D, and through the tlues E, E, F, and G, into the space H, and thence into the escape-flue I, as shown in Fig. 4.

I claiml. vThe combination, in the range A, of the ilues C, D, D, H, and I, said flues G and H being separated by the strip K, extended and 6 5 arranged substantially as shown and described.

2. The combination in the range A, of the tlues O D D E E F G H I and the damper M M', said lues C and H being separated by the strip K, extended and arranged substan- 7o tially as s hown and described.
